Answer:
By the Pauling rule, of EN
Explanation:
EN means electronegativity, the ability of atoms to attract electrons.
In the periodic table each atom, has a value of EN.
When there are two atoms bonded, you must substract the EN (the high - the low) → ΔEN
It depends on the ΔEN, that you can define a bond as ionic, covalent or metallic.
Ionic ΔEN → > 1.7
Covalent polar 0.4 < ΔEN > 1.7
Covalent non polar 0.4 < ΔEN
Two metals have always a metallic bond
Percentage yield = actual yield/theoretical yield
So divide 21.0 g by 22.7 g and multiply it by 100 to find the percentage yield
<span> The Reactants are Zinc (Zn) and Sulfur (S).
The Product is Zinc Sulfide (ZnS).
All of them are solids.
The combined masses of the reactants must be 14 grams, too. Later in
Chemistry you'll learn that's not really true, but it is for now.
Hope This Helps:)
